Specification of Letters Patent.

Patented Oct. 2'7, 1908.

Application filed February 6, 1902. Serial N 0. 92,883.

To all whom it may concern:

Be it known that I, GEORGE JOHN STE- VENS, a subject of the King ofGreat Britain and Ireland, formerly of Bradford, county of York,England, now residing at 25 East Lake road, Loughborough Junction,London, S.E., England, have invented a certain new and usefulimprovement in a combined presserfoot and guide for sewing-machines forproducing blindstitching and fancy and ornamental stitching and thelike, of which I declare the following to be a full, clear, and exactspecification.

My invention relates to a combined presserfoot and guide for'sewingmachines for producing blind-stitching, while at the same time notinterfering with the use of the machine for plain stitching, the objectof my invention being to produce a device that shall be of extremesimplicity in construction, and both easy and inexpensive tomanufacture; easy to secure to and readily adjustable upon any ordinarysewing machine, and capable of use upon the same; that will perform thework of blind-stitching, hemmin and the like, with the usual andordinary Iock-stitch of the machine, and that will perform this workupon substantially all kinds of material, however thick or thin they maybe.

The novel construction, combination, and arrangement of partsconstituting my invention will be hereinafter fully described, pointedout in the appended claims, and illustrated in the accompanyingdrawings, which form a part of this specification, and in which:-

Figure 1 is a perspective view showing my combined presser-foot andguide in place upon a sewing machine, with a piece of work folded andbeing stitched. Fig. 2, is a perspective view of the combinedpresser-foot and guide by itself, showing the presser-bar in dottedlines. Fig. 3 is a side elevation of the parts shown in Fig. 2, theinner foot being depressed somewhat to form the guide. Fig. 4 is a viewshowing the bottom of the presserfoot and guide. Fig. 5 is a front crosssectional view of the same, and Fig. 6 is a plan view of the sameshowing the parts slightly separated.

In carrying my invention into effect I provide a block A, which is soconstructed as to be readily attached to the presser-bar B of the sewingmachine by a suitable set-screw 7) instead of the ordinary presser-foot.Upon the outer side of this block A, which is provided with a rearwardlyprojecting extension A, I secure a presser-foot C, the inner side ofwhich, that is to say the side next to the needle D, is cut awaysomewhat to form a recess 0, through which the needle D may pass.

cure another presser-foot E, provided with a recess 6, on its outer facenext the needle D. I preferably construct the block A with the twovertical ribs a, a located opposite to each other upon the rearwardlyprojecting extension A and about midway of its length, and just back ofthe point of attachment to the resser-bar B, and construct the twopressereet O, E, with corresponding grooves or channels, 0 e permittingengagement with the ribs a, a just mentioned. The two presser feet O, E,may be attached to thelock A with set screws 0 6 or in any other desiredway, that will permit of the necessary adjustment hereinafter mentioned.

I provide the two presser feet O, E, with vertical slots 0 6 throughwhich the set screws 0 6 that secure the presser feet 0, E, to the blockA may pass, permitting the presser feet 0, E, to be adjusted up and downupon the block A, and to be secured in any desired position thereon.Back of the set screws 0 6 that secure the presser feet O, E, to theblock A, I provide adjusting screws F, G, which pass through screwthreaded holes f, g, in the presser feet O, E, and have their bearingagainst the adjacent face of the rearwardly projecting extension A, ofthe block A.

- In carrying my invention into operation upon machines where the workis fed from the o erator toward the back of the machine, the 0 0th H tobe blindstitched is folded as shown in Fig. '1, and placed under theouter presser foot O, the cloth I, to which the first piece H is to beblind-stitched, being beneath the folded piece and laid flat upon themachine; or the two pieces of cloth H, I, to be joined, may both befolded separately and laid the one'upon the other, both folds beingplacedunder the outer presser foot O. The set-screw 6 binding the innerpresser-foot E to the block A is then loosened, and the innerpresser-foot E allowed to drop to near the bed-plate K of the machine,in which position it is then secured to the block A, by

tightening the set-screw e.

To the opposite side of the block A, I se- The inner presser-foot E, inthe construction above described, serves as a guide for the Work, whichis fed against it, the outer face of this resser foot E, that is, theface next the needle D, being almost in line with the inner face of theneedle D, that is to say, the face toward the arm of the machine, sothat as the work is fed to the machine, and against the inner presserfoot E, the needle D must pass more or less exactly through the centerof the fold of the cloth H and not entirely through its entirethickness, from side to side of the cloth.

By simply turning the adjusting screw G, at the rear of the innerpresser foot E, the one way or the other, the point of the presserfoot Emay be moved more closely to, or away from the needle D, thus giving theadjustment necessary for sewing cloths of va rying thicknesses. It willbe obvious that instead of making the inner presser foot E serve as theguide, that in cases where the work is fed from the back of the machinetoward the operator, that the outer presserfoot 0 may be used astheguide, the work in this case being fed against it from the otherside. The presser foot C in this case will be lowered to near thebed-plate K of the machine, in order to serve as the guide, and securedin this position by the set-screw 0 while the point of the foot 0 willbe adjusted toward or away from the needle D, by turning the adjustingscrew F the one way or the other. The work will then be folded andplaced under the foot E, which will serve as the presser-foot. Or, ifpreferred, the sewing machine may be provided with two presser-bars sideby side, and the two presserfeet C, E, may be attached thereto, insteadof to the block A above described. As it is essential that thepresser-foot that acts as the guide should lie so close to the needle Dthat the latter when making the stitch can not pass entirely through thethickness of the cloth operated upon, as otherwise the stitch would showupon both sides of the cloth, I construct the recesses c, e, in thefaces of the presser-feet, just sufficiently large enough to take thebulge of the cloth as the needle passes through it. If either too largeor too small, irregular stitching will be the result.

In order that the feed of the machine, Where an L shaped feed is used,may not rub against the presser foot E, and injure either the foot orthe feed, or cause vibrations that might effect the regularity of thestitching, I form a small recess 6 in the bottom of this foot as isclearly shown in Fig 4.

Havin now fully described my invention, what I c aim as new and desireto secure by Letters Patent is 1. A blind stitching device for sewingmaeach of said feet being vertically adjustable,

whereby either of said feet may act as a presser foot. v

2. In combination, two feet attached to a presser bar in differenthorizontal planes and one of them having a vertical recess in its edgeto receive the bulge of the cloth and means for adjusting the saidrecessed foot towards and from the needle, the said presser feetmaintaining a permanent relation to each other when adjustedsubstantially as described.

3. In combination, two feet attached to the presser bar, each beingvertically and laterally adjustable independently of the other wherebyeach may be adjusted to a higher position in relation to the other andeach may be adjusted towards the needle and each having a verticalrecess in its edge near the needle, substantially as described.

4. A blind-stitching device for sewing machines, comprising a blockadapted to receive and be secured to the presser-bar of the machine, arearwardly projecting extension upon the said block, two feet secured tothe extension of the block, and means for adjusting the said feetvertically upon the said extension said means serving to fix the saidpresser feet rigidly in position.

5. A blind-stitching device for sewing machines, comprising a blockadapted to receive and be secured to the presser-bar of the machine, arearwardly projecting extension upon the said block, two feet secured tothe extension of the block, means for adjusting the said feet verticallyupon the said extension, and means for adjusting the said feet nearer toor away from each other and the needle of the machine said means servingto fix the said presser feet rigidly in position.

6. A blind-stitching device for sewing machines, comprising a blockadapted to receive and be secured to the presser-bar of the machine, arearwardly projecting extension upon the said block, vertical ribs uponthe said extension, and two feet adjustably secured to the saidextension with means for fixing the presser feet rigidly in position,and having grooves or channels for engagement with the said ribs.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

GEORGE JOHN STEVENS.
